Specification of Letters Patent.

Patented April 30, 1907.

To all whom may concern;

Be it known that l, WILtjL-iii H. Lewis, a citizen of the United. States.- residing at Roanoke, in the county of Rounoke rind. State of "irginis, have invented certuiu new and usei ful Improvements in Brakes, oi which the 5 following; is a specification, reference being i My invention relates to brakes for railway or other cars, sndhas for its object to pro l vide new and improved moons for supporting; the bmke-sl1 es and by which. the bruins shoes only be applied to the wheels. l

To this end my invention consists in on. improved construction of bloke-beam by 1 which the weight of the hezuu uni-y be "very considerably reduced without'loss oi strength, as will appear from the follow .1 d' seripi'ioni \Vhat l regardas new is i th in the claims.

in the accompanylug drawing is a rear view of a. portion of 1?. trating my improvemerits; Fin, 7: View thereof; Fig. 3 is on r it l'lO parts being in seotion; uud K on line 4 -l' of Fig. :2.

Referring to the drawing" part of a truck-ironic, and n one end thereof.

89 indicate the l)1z3,l((ill3:tds, which may be of any suitable constriu-tiou. 'ihey are suspended from the trurk-lmine .3 b irrups' thev are fitted upon the ends of the ()l11])lSSh)i\- member hereinafter described,---+suit:ible l sockets being provided in them for that pur- I ose. The broke-beam is con'iposed of u l l JIOD compressionqneniber ll, u. :lulc'rum-posl l or strut 12, and two rods l3- i-l, the ends ol l which are connected to the blVLkC-llQZlKlS S l 9, one at each side of the horizontal lL-i. erof the compressioil-member, us drown in Figs. and 3, so that said l'luugc ol' thecorupressi u- 5 member is included between them. Said rods extend around one inner end or the l'ulcrum- 0st 12, the outer end oi whirh is couj necte centrally with the coorpression-mcuiher 11, as shown in 2, so that said l)ili'l.\ i together form it truss, the rods lt+--1-l ili'ilt the tension-moniker thereof. The 1 nor eon ol fihe fulcrum-post 1'2 is provided wi 1h s. or grooves l5--l(3 to receive the rods l3---l-l as shown in Figs. 3 and 4, and thereby bold f plied to lhe couipre both sides ol' sand web.

jper end of the chain 18 is connected by a be t 19 with u spriugerm 20 secured to the trucklrruno, {is shown in .l 'ig. 3.

As lllllSlltliOLl in Fig. 4, the compression illilllltl" T-shaped in oross-section, having u. horizontal web 21 which is perpendicular 3 to the inise of the coinpression-mernber.

Said web 21 is fitted in a suitable groove in the outer end of the post 12 end is secured therein. by rivets or other suitable means.

shown in Fig. 3, the rods IS -14 are connected will] the bruke hezuls at opposite sides ol' the web 21, so that tension is up siouoneruber equally at Z-l; indicates :i broke-lever, which, as best i Sllififll in hire. :3 and 3, is tuloruined upon a j pin 25 titled in the post 12. The lever24 posses through :1. suitable slot 26 in Said post. which is ol sulherent length toperniit l said lever to ploy 'l'reely therein at the proper zine-lo. The lever is connected up for oporation in the usual way,its lower end he 1 mg connected by at rod .27, or other suitable 11mins. with the brolie-mechanism at the opposite end of the lruek, or with that of unothcr truck. while its upper end is connected wilh suitable eeluatiug-ineeluinisni.

By l he eouslruoliou described, I provide a i very: light but strong bruke-beznu, which, in

Pructire, l barre found to be equal to thet'of other beams having; lil't per cent more msteriul. and it iuecls every requirement for pro required for high-speed brakes.

So for us the broader claims are concerned,- iu invention is nol rvsl ricleu' lo the specific embodiment thereo illustrated in the drowlugs, but includes uuuliliculious or variations which do not iilepurt from the spirit of the in Yeuliou.

That which if claim as my invention and desire to secure by Letters Patent is, a
